I compiled the 100a for my camera. the compilation worked fine, but for some reason the chdk doesn do much more than the "firmware upgrade" to 1.0.1.1 and restart the camera. i guess i have to wait for a pro to compile the sources.
You might not have been using the new sources I posted, I had a bug in the old ones that had the wrong memory address for generating one of the stub files.
...
I'm using the 1.00A FW on an IXUS60 (SD600) and all seem well, but as you say the movie functions seem to be absent, but that's a minor point!
Movie functions aren't implemented on either 1.00a or 1.00d yet. If you want to have a stab go ahead but you'll need to compare code with the sd450 since the sd630 doesn't seem to have movie implemented either.
I just installed it on my SD600 (1.00A) and no RAW here either. Plus the bracketing script seems to be stopping after the first shot.
Bracketing won't work since chdk can't change the Ev/ISO/Tv yet.
I've installed this on my SD600 (1.00d) and I see the blue thing pop up telling me the version..
I get the battery meter (awesome) and the sd card memory guage.. which is great also!
But I absolutely cannot find any other features... all I'm seeing are some new things on my display, nothing else looks different to me .. I must be doing something wrong
Hit the little 'print' button above the dpad and then it will be in ALT mode, then hit meny and you can access all the crazy features.
thanks a very lot Novex, great work
i compiled it for 100a on linux and it "works" but doesn't do raw (as you described), movie does seem to work (it saves a movie, or is there any special feature of chdk for movies?)
any suggestions how i could help?
i'm not experienced in this stuff, but hey i succesfully compiled it 
if others want to try 
ixus60_sd600-100a-beta_build.zip - 0.22MB
credits go to Novex, i only compiled it 
You can go through and check my addresses? I still have no idea why nothing capturing works - things in capt_seq.c appear to be fine (though I found one wrong address, oops). I guess the next thing is going through and manually checking the stubs I guess.
I haven't had much time to work on it lately, work called me in a fair bit this week. I'll take a deeper look over the weekend.
